Hi all,
I have two questions about how I should run an event study. First, I have a staggered implementation of policy but do not know how I should run an event study. What I am doing is as follows:
1- I created an event variable which is equal to -3, -2, -1, 0 , 1,2,3,..
2- I run the following regression:
reg output ib0.event , r
event is my event variable from the first stage.
my question is whether my approach is correct or not. I would really appreciate it if someone can tell me how I can run an event study with lags and leads.
My second question is what happens if some states after a while cancel that policy. So some states change their status. I would really appreciate it if you can tell me how I should deal with it. Thank you very much for your time.
Best,
Mori
